See The Cover for James Rollins’ Next Sigma Force Thriller, ‘Crucible’

With no new novels slated to come out in 2018, fans of James Rollins’ Sigma Force series will have to wait until 2019 for Crucible, his next full-length adventure. However, if it’s any consolation, it sounds like his next book will be well worth the wait . . .

Originally titled The Hammer of Witches, Rollins’ 14th Sigma thriller underwent a title swap toCrucibleearlier this year. The book will follow The Demon Crown(2017), which was praised by critics and readers alike, and will feature a particularly dangerous storyline for Commander Gray Pierce, who is front and center in the plot description, which you can read below.

In the race to save one of their own, Sigma Force must wrestle with the deepest spiritual mysteries of mankind in this mind-expanding adventure from the #1 New York Times bestselling author, told with his trademark blend of cutting-edge science, historical mystery, and pulse-pounding action.

Arriving home on Christmas Eve, Commander Gray Pierce discovers his house ransacked, his pregnant lover missing, and his best friend’s wife, Kat, unconscious on the kitchen floor. With no shred of evidence to follow, his one hope to find the woman he loves and his unborn child is Kat, the only witness to what happened. But the injured woman is in a semi-comatose state and cannot speak—until a brilliant neurologist offers a radical approach to “unlock” her mind long enough to ask a few questions.

What Pierce learns from Kat sets Sigma Force on a frantic quest for answers that are connected to mysteries reaching back to the Spanish Inquisition and to one of the most reviled and blood-soaked books in human history—a Medieval text known as the Malleus Maleficarum, the Hammer of Witches. What they uncover hidden deep in the past will reveal a frightening truth in the present and a future on the brink of annihilation, and force them to confront the ultimate question: What does it mean to have a soul?

For readers struggling with the long wait between Sigma books, there is good news. We reported last month that Rollins has signed a new four-book deal with William Morrow, his long-time publisher, ensuring new yearly releases through 2023.

Fans excited to get their hands onCrucible can pre-order James Rollins’ next Sigma Force thriller wherever books are sold.
